A few months ago, we wrote about [using Elm Native UI in production] for our
mobile app [Purple Train]. Today we're happy to announce that the code is
publicly [available on GitHub].

Purple Train is the first native mobile app in the App Store and the Google Play
Store written in the wonderful [Elm language]. Take this as an opportunity to
see how we built a "real app" using the experimental [elm-native-ui].
